Product Description:

The 1070084674-GA1 servo drive module is produced by Bosch Rexroth Indramat as a member of the DM Servo Drives series. It converts shared bus energy into a regulated three-phase output that controls torque, speed, and position on individual automation axes. Within multi-axis packaging machines, pick-and-place arms, or gantry stages, the drive supplies closed-loop motor power while exchanging status and diagnostic data with the higher-level motion controller. Its role is to provide responsive motor control in systems where coordinated axis movement and repeatable positioning are required during continuous machine operation.

The power section accepts an input of 670 VDC and draws 8.5 A DC from the common bus. It can operate from either a regulated DC link or an unregulated 715 V variant, allowing the rack to work with actively stabilized or passive rectifier modules. Internally, the IGBT bridge switches the link at 8 kHz and synthesizes a three-phase 400 V output. Nominal motor load is handled at 8.2 A, while the drive can deliver a controlled-limit current of 14 Arms for brief accelerations. Velocity commands are supported over an output bandwidth of 0 to 800 Hz, enabling high-speed spindle or servo operation. Position feedback is processed with a 32-bit internal resolution, allowing fine interpolation steps during motion control.

Peak overload capability is 22 Arms, giving additional headroom for rapid indexing moves before the controller folds back to continuous ratings. Thermal design confines power loss to 156 W, and the 50 mm wide housing weighs 6.0 kg, permitting dense side-by-side mounting inside a shallow cabinet. Control setpoints travel through the SERCOS fiber-optic interface, while real-time current regulation uses a 20-bit stage resolution for smooth torque transitions. A 24 V control supply at 1.03 A keeps the logic section active during mains shutdown, which supports status retention and orderly control behavior. Front-panel terminals accept the drive’s field wiring without expanding the installation footprint beyond the narrow module width.
